y snnnrnorntnne'GULTIVATOR To aZZw/'wmt may concern? Be it-known that I, Louis JAooBs, ra

citizen of. the United States, residing yat' Stevens-Point, Portage county, lfVisconsin, vhave invented certain'new and useful lImprovements in Self-Propelling Cultivators,

of which the following is a specification.

My invention relates to .farming implements .and'machinery and has particular reference to a horseless cultivator and the provisions in connection therewith for car-- rying the driving power on the `cultivator and for simply and promptly making'the short turns at the ends of rows that this form of implement usually must. make. AThis invention consists in the novel construction, combination and arrangement of parts, all as hereinafter described in detail,` illustrated in the accompanyingdrawing, and more parl ticularly pointed out in theappended claim.

. In the drawingI Y Figure 1 is .a planview, partly broken away, of a cultivator embodying my invention."V `v` f.

Fig. 2 is'a side elevation. Fig 3 is an enlarged horizontal section Voiran enlarged scale of the notor driving shaft clutch mechanism connection for eac-h i 1 of the driving wheels.- i

ln the several views 1 and 2'are'the wheels of the cultivator carried in the usual aXle 3.

on whichaxle are-also pivoted' for the usual vertical and horizontal pivotal movements the cultivatorshovel beams, details of said aXle connection not shown in this connection. To the inner sides of the wheels are secured internal. gear-rings4 and. 5. These maybe secured to the wheels in any suitable manner, as, for instance, by clamps or 'brackets 6, 6 that clamp the gear-rings to spokes-7 of the wheels. On the aXle 3 is mounted a frame 8 that carries any suitable type of l internal explosion engine.

In the present instance the'driving power is represented'by a pair of engine-cylinders 9 and 10 that are connected in the well known manner with a crank shaft 11 each end of which is reduced to provide a yclutch mechanism carrying 'spindle or shaft portion 11. At the oppol site ends of said driving shaft and secured to the latter or made a` part thereof are fly' wheels constructed and arranged to serve as clutch members. One lof these identical iy wheels is shown in section in Fig. 3 and is designated by the numeral 12. 13'representssthe radiator tank and 14 thevuel tank vthe usual beams 22 and 23 which are erally provided with branches 24 an Specification of Letters Patent.

. A for the engine, both being connected in the usual manner not shownin. detail.v

From opposite `sides of the frame 8 extend toward each otherseat-carrying arms 15 and 16 which form an angle over which is mount- 'of vegetation to. be cultivated. v0n the axle 3 are mounted in any well lmown manner .eny 25 onthe lower ends of which are shovels 26, 27, 28, and 29.- 0n each of the reduced por-v tions '11 of the driving shaft 11 is loosely mounted a sleeve 30 to oneend of which is keyedJa' pinion l31 that is'in mesh with the drivingwheel internal gear ring. ()n the opposite' end of said sleeve is splined for longitudinal movement thereon a movable clutch-member 32 which has thereon a hub 33 with a peripheral groove 34 therein that 'is engaged Lby a ring 34 that is loose in its groove and .has pivoted thereto in the well known manner the arms of a fork 35 of a clutch-member operating lever 35 that is of elbow form and has its angle portion ulcrumed at 36 to any suitable stationary part. The end or arm of this lever to which the -force is applied fromthe operators lever is .distinguished from its fork-'portion35 by the numeral '37. To the arm 37 is connected -at 38 a rod 39 that is pivoted at 40 to a hand-lever 41 which operates the clutch for the wheel 2. The lever 41 is fulcrumed at A42.. The movable clutch member 32 is of conical form and is normally held in engagement .with the correspondingly hollowed out Hy wh'e'el which is the engine driving shat'clutch member,l by means of a coiled spring 43 interposed between a flange 44 on the sleeve 30, between which and another somewhat similar lange 45 a framen portion .is engaged to prevent longitudinal movement of said sleeve. The operators lever for the wheel 1 is designated by the numeral 46 and is connected in the same manner as the lever 41 is connected with the clutch mechanism for the wheel 2 as described above. On the forked end 35 of each clutch elbow lever is a projection or lug 47 which serves as a brake shoe and is brought into Contact with the internalv gear ring to apply a brake to the wheel vwhen the movable clutch member has been moved out of engagement with the engine shaft clutch memben By 'swinging the elbow lever in its release movement suciently to apply the brake shoe or lug with force enough to entirely stop rotation of' the wheel the stoppedl wheel may serve as. a pivot around which the other wheel moves in making a short turn. To the shovel beams are'secured the usual plow handles-by means of which the operator from his seat is enabled to control the shovel beams which may also be controlledby the feet of the operator when his hands are otherwise engaged.

I claim as my invention-` The combination with a pair of combination driving and steering wheels and an axle said clutches and levers and operable simultaneously therewith to apply the brake to a wheel after the clutch mechanism therefor has been released from the engine shaft and swiveled wheels upon which a driver is supported in the-rear of said driving and steel ing wheels.

In testimony whereoil I have hereunto signed my name.
